From: Josef Bacik Subject: [PATCH 6/6] Gfs2: fail if we try to use hole punch Date: Mon, 8 Nov 2010 15:32:07 -0500 Message-ID: <1289248327-16308-6-git-send-email-josef@redhat.com> References: <1289248327-16308-1-git-send-email-josef@redhat.com> To: linux-kernel@vger.kernel.org, linux-btrfs@vger.kernel.org, linux-ext4@vger.kernel.org, linux-fsdevel@vger.kernel.org, xfs@oss.sgi.com, joel.becker@oracle.com, cmm@us.ibm.com, cluster- Return-path: In-Reply-To: <1289248327-16308-1-git-send-email-josef@redhat.com> Sender: linux-kernel-owner@vger.kernel.org List-Id: linux-ext4.vger.kernel.org Gfs2 doesn't have the ability to punch holes yet, so make sure we return EOPNOTSUPP if we try to use hole punching through fallocate. This support can be added later.
